FWIW, for most navigating on our boat (Lake Erie), I use Navionics on an iPad, which is in a waterproof case and mounted with a RAM mount to the steering pedestal. Power use is an issue, so I have two power packs for when the battery is low. (I could wire a charge cord to the iPad mount, but this has not been necessary.) When the iPad nearly runs out of juice (about 3 or 4 hours), I plug in a powerpack. That gets me about 3 more hours, which is usually enough for the type of sailing/distance racing that we do. If not, I have a second power pack, which can be used while the first one is recharging.
The reasons I went this route are: 1) ease of use; and 2) technology changes so fast any more that I did not want to invest in an expensive nav system only to discover that it is obsolete by the time I hook it up. (I still have a Loran unit in my basement.) The system is simple, but it works fine for me. I don’t use autopilot, which would obviously make a big difference.

The phone. This is CHEAP and good. I like the Navionics charts and their nav program is very easy to use. I can see no reason NOT to have it unless you don’t have a phone. That said, there is no way I would ever trust a phone as a primary nav instrument. The battery gets eaten fast using this app, it is hard to read in sunlight, it is not waterproof, it is not designed to be wet and banged around, and you can always get a phone call right in the middle of navigating the narrow rocks passage or maybe some IOS update will kick off. You are of course limited by screen size and feeding AIS or instrument data into a phone takes some doing. 2. OpenCPN. My favorite by far. It is an excellent program, charts are free, and nothing beats a nice 15 inch color display. I feed AIS info into this program and it is very useful with changeable CPA alerts. Radar overlay is possible. What I don’t like is all about the PC: It is not marine gear and cannot get wet. It sits below out of the sun, wind, and rain where I can’t see it from the helm. The current draw is 2x-4x higher than a dedicated plotter. Depending on your IT skills, you have some exposure to PC malfunctions at the worst possible time. I have mine working pretty well, but any PC can have issues. One reason my PC works well is it does NOTHING ELSE. It is never ever connected to the internet. No games, no browsing, nothing but nav EVER. 3. Marine GPS plotter. I have a CP180 at the helm. The CMAP charts are mostly excellent, but some areas are less detail than NOAA and some are more. It has a nice daylight readable color display, it is waterproof, and it right in front of me at the helm. The power draw is low and reliability is high. There are multiple NMEA inputs and outputs, so linking to the VHF and AIS is easy. The bad points are paying for CMAPs and the screen size. With a 5 inch screen, you can see detail or see a long way around you, but not both. For one example, to get good enough resolution to see the narrow channel into Kent Narrows well, you are basically zoomed in to about 200-300 feet around the boat. I bought it to save power and to have a dead reliable screen at the *helm*. I am on autopilot about 80% of the time, but the 20% I am not tends to be the trickiest navigation where I need to see around me and see the plotter with my hand on the wheel. The CP180 has a fishfinder option I may get off FleaBay one of these days.
